Question about Haier HPR09XC7 Portable Air Conditioner

1 Answer

Why won't my unit come on?

I have two of the same units. Brand new, only used one summer. Never had to drain, both worked great. Not dirty inside either. Neither one will turn on now. Tried several different power sources. On one unit the red light just flashes a couple of times then shuts off. The other unit the display screen lights up for a second then shuts off. Any ideas?

SOURCE: No power to my window ac unit

Hi, and yes, I do have some ideas that may be of help to you. I have to ask this first of course, have you checked to see if you have power to the unit at the receptical and or breaker? May have not had equalized pressures in the system causing it to draw high or excessive amperage on start up and tripping a breaker? If you haven't checked this, please start there for me? "Thank You" If you do have power to the unit and lets say as I don't no, can you hear anything when you call for cooling with the control T-stat on face of this unit, or nothing at all is happening? Lets say you have power but nothing is taking place as I think that is what you have said, It may be as simple as a control wire at the control connections is loose or may have come off or even burned off as they do pull high amps. You would have to remove knobs, front face cover, and may even have to remove all perimeter screws around the front inside, as the way to excess controls on a window unit, it slides into a case..Anyway, If you are willing to go these extra steps we may be able to locate what the cause of the problem fairly easy. If this unit is a a/c only and no heat, you will have many less controls to worry about checking out. To be honest, without a mulitimeter and some knoledge of electrical experience, It will be a pretty much take a good look over all parts and wiring for you? As look for any signs of hot spots in the exposed wiring, burned areas on controls right where you're main wires or power cord comes into the thermostat control. This would be the begining of the cooling cycle to start the unit on a call from the stat. You will need to find the main power which I would be certain this is a 208/220, 230, 240, volt unit.Wiring would consist of 2 hot legs, maybe red and black with a possable white and for sure a solid green for grd. coming out this power cord.Unit is most likely on a double pole 30 amp circuit breaker. Be careful around capacitors even with the power off to unit as they store enough volts to send you into cardiac arrest or give you a heck of a jolt as I tend to find out on occation when I forget to discharge one before testing it.You can use a screw driver to touch across terminal to the other side terminals and this will discharge them. Basicly, we need to determine if there is the right voltage coming in to the control, is it leaving the control when you turn it on? With out a meter, if the control is intermittently operating, you should hear or even see the condenser/indoor fan motor try to start. Lets stop hear, as if you have power to this control and nothing at all is happening, this control stat has probably failed on you. If you are able to check any of the things, breaker, any power coming out of the control at any point to control to ground, get back to me. I tend to give rather long solutions for my people out there, but we can solve this together I am sure. So I will stop and wait for an update from you.

SOURCE: the unit worked fine when

I have had a problem like this in the past you can try taking the electric access panel usually on the side of the equipment. then look inside you will see a wiring harness inside and it literally takes nothing to bump it loose. This happens when people move these units they are pretty fragile and can be tempermental. Make sure the unit is unplugged while you adjust the wiring harness. If that deosnt work your display board is probably bad. Hope that helps

SOURCE: Water is dripping inside the

this sounds as though you need to service the drain pan.. you will have to pull the unit out a bit to access it . Under the evapator coil the one that is inside the house you will see a pan under it Look for a drain hole or pipe and clean it out.. you can put a bit of Clorax and warm water down the pan but rinse it out as well. then just be certain that the unit is tilted to the outsid eabout 1inch or so . Hope this helps let me know Jon

I have a panasonic split system in the kids bedroom its an ECONAVI indoor unit is CS-E9NKR we have not used this A/C since last summer, now the compressor will not start, only the indoor unit operates

Typically on a mini split the outdoor unit is powered and the indoor unit gets its power from the outdoor unit. If the unit is a year old you might have lost your charge. Look at the connections at the indoor unit and outdoor unit. You will typically see oil or a dirty area on your copper were there is a leak.

Water leaking from base of unit

Check the drain it must be plugged. Check the evaporator coils for exessive ice build up on the coils, you may have a dirty filter and not getting enough air flow to keep ice from forming on the coils. The unit should have a drain built in it under the evaporator coils inside the unit. If it is a central air the evaporator is usually above the furnace. This drain pan may be rusty and leaking as well. You may have to unscrew a panel or two depending on how your unit is installed to get to the drain pan.

Is their an interior pan inside the coil??? If the drain is not clogged, the air is working great. I was told the interior pan is just tipped. Now I am told their could be a crack in another interior pan...

With out inspecting the pan its hard to say. But a secondary drain pan can be placed under the unit or the primary can be replaced. Just ask for the original part once it is replaced.

Same issue but how do I get the cover off the indoor unit?

do u have water draining on the outside wherever they ran the drain lines from each unit? if not , maybe they werent pitched correctly and are overflowing, those units have a tiny drain pan and must be pitched correctly on the install. Call a different contractor to check it out! And only during the summer because those units, as any AC does, remove a great deal of humidity, it isnt that humid in other seasons.

Working right and in a safe manner?

The condensation has to be going somewhere if not out the drain tube, if unit is working correctly, just hope it's not running down inside your window frame and rotting something. Keep looking, I would.
